Pololu

This gearmotor is a miniature high-power brushed DC motor with a 75.81:1 metal gearbox. It has a cross section of 10 × 12 mm.
Key specs at 6 V: 400 RPM and 120 mA with no load, 1.6 kg-cm and 1.6 A at stall.

The GP2Y0A60SZ distance sensor from Sharp offers a wide detection range of 4″ to 60″ (10 cm to 150 cm) and a high update rate of 60 Hz. The distance is indicated by an analog voltage, so only a single analog input is required to interface with the module.

Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V an

This electromagnetic transducer is a compact way to add sound to your embedded project: just supply it with a PWM signal at 4 V to 6 V and it will produce sound at the frequency of the supplied signal from an opening on the top.

This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

The Pololu 3pi robot is a complete, high-performance mobile platform featuring two micro metal gearmotors, five reflectance sensors, an 8x2 character LCD, a buzzer, and three user pushbuttons, all connected to a C-programmable ATmega328 microcontroller.

This device is a programmer for AVR-based controllers, such as our Orangutan robot controllers and the 3pi robot. The programmer emulates an AVRISP v2 on a virtual serial port, making it compatible with standard AVR programming software. Have a TTL-level

This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and sta

This semiconductor gas sensor detects the presence of LPG, isobutane, and propane at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 10,000 ppm and combustible gas from 100 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontro

This board is a simple carrier for Allegro’s ±30A ACS714 Hall effect-based linear current sensor. This version accepts a bidirectional current input with a magnitude up to 30 A. The output is an analog voltage (66 mV/A) centered at 2.5 V with a typical er

This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 V from an input voltage as low as 1.5 V, all in a tiny, 0.42" x 0.88" x 0.23" package. A trimmer potentiometer lets you set the boost regulator’s output voltage to a v

This small digital distance sensor detects objects between 2 and 10 cm (0.8" and 4") away. With its quick response time, small size, and low current draw, this sensor is a good choice for non-contact object detection, and our compact carrier PCB makes it

This small digital distance sensor detects objects between 0.5 and 5 cm (0.2" and 2") away. With its quick response time, small size, low current draw, and short minimum sensing distance, this sensor is a good choice for non-contact, close-proximity objec

This 12-inch (30-cm) cable has 26 AWG wires with a 3-pin female JST PH-style connector that mates with the connector on 3-pin Sharp analog distance sensors. The other ends of the wire are terminated with male pins for 0.1" housing.

This RC switch converts hobby radio control pulses to digital on/off signals and has an integrated medium, low-side MOSFET that allows it to drive moderate loads (up to around 15 A), such as lighting or small actuators.

This small hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is the smallest stepper motor we carry.
